Thanks, will check out the 'tracks'.
Kreisel -- oh, as in Miller & Kreisel (M&K) -- yeah I remember him/them
The Goliath subwoofer -- oft coupled with the iconic Visonik "David" minispeakers.

[Cliff Clavin aside]: -- although the subwoofer concept way predates M&K. Heathkit, e.g., had one in the early 1950s (SS-1B) to add on to their small (and halfway decent, actually) two-way SS-1 "bookshelf" loudspeaker.

(imaging per se wasn't a "thing" in the days of mono, so the SS-1B also added a supertweeter).
